Frequently Asked Questions

BAC is estimated using the Widmark formula: BAC = (Drinks × 0.6 × 100 × 1.055) / (Weight × r) - 0.015 × Hours, where r is 0.73 for males and 0.66 for females.

In most US states, a BAC of 0.08% is the legal limit for driving. At this level, impairment is significant.

This calculator provides an estimate. Actual BAC depends on many factors including metabolism, food consumption, and individual differences.
